What is the difference between 52mm and 54mm (glasses)?

Question

I am going to buy this pair of glasses: http://www.eyewearplanet.com/ray-ban-eyeglass-frames-rx5098.html And on the page it gives you two choices. 2034-5215: 52 mm Lense Diameter and 2034-5415: 54 mm Lense Diameter. What is the difference between the two?

Thanks!

Answer 1

2mm!

Answer 2

Each lens will be 2 mm wider in the 54 mm, giving an overall difference of 4 mm in the width of the frame...that's about 1/4 of an inch.

Total  width of the 52-15 will be 119 mm ( 4 3/4 inches )

Answer 3

2mm!
